Intravascular T-cell lymphoma with bowel involvement: Case report and literature review
Bibliographic record
Abstract
Intravascular lymphoma (IVL) is a rare form of non-Hodgkin lymphoma characterized by massive proliferation of large, neoplastic cells in small- and medium-sized blood vessels. Most cases of IVL are of B-cell immunophenotype; fewer than 15 cases of T-cell IVL have been reported. A 23-year-old male presented with acute abdominal pain, fever, and tender lower abdomen. Pathology at laparotomy revealed infiltration of colonic vessels with large lymphoid cells compatible with IVL. We reviewed all cases of IVL diagnosed at the Queen Elizabeth II Health Sciences Centre in Halifax, Nova Scotia, from August 1992 to August 2002. A literature review was also performed. Five additional cases of IVL were identified at this institution during a 10-year period. Three patients presented with neurological symptoms, and two with abdominal pain. In 4 of 5 cases, patients died of lymphoma within 3 months of presentation; one patient experienced a 10-month remission. While visceral involvement with IVL is common at autopsy, IVL presenting as an acute abdomen in an immunocompetent patient has not previously been described. Among the 15 cases of T-cell IVL reported in the literature, only two occurred in people under age 30. Given the rarity of T-cell IVL, it is remarkable that three cases of T-cell IVL have been diagnosed at our institution during a 10-year period.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
